I feel like I've tried everything, from adding the registry key that MS mentioned (MoSetup) and the DWORD key to the LabConfig key. I've added both of those sets of keys to my Windows 10 installation and to the X: drive when attempting to install Windows 11. Nothing seems to work. Sorry, I'm shortening that explanation up a little, but that's basically it.
Any hints on trying to get it installed on my PC?
EDIT: I just realized that I'd been attempting to perform an "Upgrade" vs a Custom install. All instructions call for a Clean Install, so it looks. is there actually a way to upgrade? Using the Upgrade option, I got no further before I got a compatibility check. With the Custom option, I got to the screen where I can remove and create partitions. I'm afraid that once I create new partitions, effectively formatting my computer and losing everything, I might end up getting the system requirements error once finally get to the install screen, and that I'll have to restore my computer from a backup, back on Windows 10. Any truth to that?
